Floyd Mayweather's adviser said he expects an announcement within the next few days, likely before Christmas, on the boxer's next bout.

The Grand Rapids native intends to fight May 4 in Las Vegas, though none of that has been finalized.

Most likely opponents are Robert "The Ghost" Guerrero or Saul "Canelo" Alvarez, both of whom are promoted by Golden Boy Promotions, with which Mayweather has a working relationship.

Leonard Ellerbe, CEO of Mayweather promotions, said today that he expects to have the fight finalized in the next few days.

"Floyd just wants to fight the biggest fights out there," Ellerbe said, though he declined to identify the targeted opponent or confirm that it would be either Guerrero or Alvarez.

"We already know who the players are," Ellerbe said.

Mayweather last fought in a May 5 win over Miguel Cotto.

Since then, several of his top potential challengers have lost and fallen out of contention for the fight, most notably Manny Pacquiao twice -- including a knockout loss last week to Juan Manuel Marquez -- and Amir Khan.

Mayweather turns 36 in February.

"I think he's re-energized," Ellerbe said. "He's just looking to go out there and show the whole world he's the best out there and will continue to be the best out there."
